Title:
MANUFACTURING METHOD OF STACKED CELL
Document Type and Number:
Japanese Patent JP2020072019
Kind Code:
A
Abstract:
To provide a manufacturing method of stacked cell capable of restraining short circuit.SOLUTION: A manufacturing method of stacked cell includes a step of cutting an electrode laminate, having a positive electrode layer, a negative electrode layer, and an isolating layer interposed between the positive electrode layer and the negative electrode layer, by means of a cutting blade. In the step of cutting, assuming the angle formed by the direction of travel of the cutting blade and the interlayer direction of the electrode laminate is θ, the thickness of the isolating layer is t, the amplitude of vibration generated in the cutting blade when cutting the electrode laminate is A, the angle formed by the direction of vibration generated in the cutting blade and the interlayer direction of the electrode laminate is θ, and the maximum burr dimensions when cutting the electrode laminate at θ=90° by means of the cutting blade is h, the cutting step satisfies the following formula (1). t>hsinθ+Asinθ... (1).SELECTED DRAWING: Figure 5
